A growing interest is on the biological remediation of pollutants with the added benefit of generating electricity in microbial fuel cells (MFCs). Therefore, the analyses of suitability and potential of full-strength paper ...

Geometric optimisations are presented for the UTD in SuperNEC which is a commercial electromagnetic
software package. Path finding optimisations rapidly find propagation paths of
electromagnetic waves by using back face ...

The South African hedge fund industry is reported to have had R52 billion (USD 4.8
billion) assets under management at the end of December 2013. This compares to
the global industry which is reported to have surpassed ...

In this thesis, we analyse reasons for poor image quality on the Southern
African Large Telescope (SALT) and we analyse control methods of the
segmented primary mirror. Errors in the control algorithm of SALT (circa
2007) ...

South Africa hosts a large number of non-native freshwater fishes that were introduced for various industries. Many of these species are now listed under the National Environmental Management: Biodiversity Act (NEM:BA) ...

Zimbabwe has a rich and diverse minerals resource base that could be an important contributor to sustainable growth and development. The sector has rebounded dramatically from the hyperinflation economic crisis (2006-8) ...

Since the industrialization of platinum group metals (PGMs), particularly platinum (Pt), palladium (Pd) and rhodium (Rh), the control of trace impurities in these metals has become vital. Reliable analysis of impurities ...

Increasing concerns over environmental and geo-political issues on resources’ sustainability
have driven the industries to shift their efforts to produce chemicals from renewable biomass.
Amongst the lignocellulosic ...

A multi variable control strategy for a grinding circuit at East Driefontein has been
implemented by others and has enabled it to operate under stable conditions. The next
development needed was to find conditions under ...

In view of the growing concerns over depleting energy resources, alternative renewable fuels such as biodiesel have been identified as a possible means of addressing the short fall in energy supply. The source of feedstock ...

The search for suitable sintering additives for boron suboxide (B6O) materials which could improve densification, reduce sintering temperature and tailor the microstructure has been of great importance. In an earlier study ...

The research report is premised on three aspects which are critical in the heavy mineral beneficiation. These aspects are classified as (i) understanding the densimetric profile of the available ore body, (ii) understanding ...

Conversion of biomass to useful bio-products is a lengthy and often inefficient process. Research
has looked at the conversion of cellulose to ethanol by means of termite bacterial consortium in
fluidized bed bioreactor, ...

Wastewater is one of the major problems to human life because it contains contaminants (such as viruses, worms, bacteria, etc.) which pollute the environment and causes various diseases (like cholera, dehydration, skin ...

Most coal seams in the Waterberg Coalfield contain medium to high levels of phosphorus in coal. Thermal coal, which has a lower value than metallurgical coal, is produced from these coal seams. Metallurgical coal used as ...

Namibia Custom Smelters treats complex copper concentrates. At the time of the research, three
furnaces were in operation namely, the Top Submerged Lance Furnace, the reverberatory furnace
and the converters. All these ...

The Integrated Gasification Combined Cycle (IGCC) is a promising technology in the power generation industry to increase efficiency and reduce environmental emissions associated with fossil fuels. The performance of the ...

This research investigation focused on the quantitative comparison of Ti-6Al-
4V with respect to two cutting fluid delivery systems: Flood Coolant and
Minimum Quantity Lubrication (MQL). The analysis was based around ...

Reinforcing bars produced at ArcelorMittal via the Electric Arc Furnace (EAF) process route and the Rod Mill are breaking during application. This is due to the high residual content of the material, which produces an ...
